FRANZ JOSEF REINISOH, OF LEMBERG, AUSTRIA-HUNGARY.

SMOKE-CONSU MING FURNACE.

SPECIFICATION forming* part 0f Letters Patent No. 564,649, dated July28, 1896.

Application filed February 20, 1896. Serial No. 580,070. (No model.)

To all whom, t may concern:

Be it known that I, FRANZ JOSEF REINIsoH, asubj ect of the Emperor ofAustria-Hun gary, residing at Lemberg, in the Province of Galicia,Empire of Austria-Hungary, have invented certain new and usefulImprovements in Smoke-Consuming Furnaces for Purposes of Central Heatingand Ventilation, of which the following is a specification.

This invention relates to a smoke-consuming central-heatin g furnace 5and it consists in the particular construction and arrangement thereof.

Figures 1 and 2 show vertical sectional views, and Figs. 3 and 4cross-sections on the lines y and y z of Figs. 1 and 2.

1 is the casing of the furnace, built of fireproof material.

2 is the fireplace.

3 are the grate-bars of thel basket-shaped grate.

4 is the reserve grate, which has a solid bottom with side walls 5 and afront wall 6. It forms a drawer without a back wall. The bottom ascendstoward the front wall 6, so that a bottom surface is formed which isinclined toward the inside. The front wall 6 is tightly closed by adoor.

The back Wall of the furnacehas a recess 7, into which the free rearedge of the gratebottom 4 and the free edges ofthe side walls 5penetrate, so that when the reserve grate is inserted the drawer iscompletely surrounded, and this drawer incloses the lower part of thefire-grate 3 in such a manner that the same is sunk partly in the drawer4, eX- cept for a small space 8, and serves for fluid fuel or as adouble grate for eecting a complete combustion of the other fuel, as theside walls 5 of the reserve grate cover only partly the side walls 9 ofthe fire-grate 3, and the glowing piecesy of fuel falling through thegrate 3 will be completely consumed upon the reserve grate 4.

The ash-box is shown at 10.

11 is a backwardly-tapering cover.

12 is a tightly-closin g door for charging the furnace; 13, the ash-pitdoor.

14 are clearing doors or channels for the spiral pipes to be describedlater, said chan nels serving at the same time as supports for thepipes.

16 is a funnel-shaped seat for the grate 3; 17, two interior partitions,which, with the outer casing, form a double casing.

18 are air-channels provided with revolving valves 19, which are turnedfor the purpose of regulating the inlet of air. These channels 18 arearranged on both sides between the casing 1 andthe partitions 17 andpreferably the same number on each side, and all issue in a preliminaryheating-space 20, where the fresh air which has entered through 18 comesin contact with the heatingpipes 21, passing in the direction of thearrows, Fig. 2, and enters the heating-room 22. The branch pipes 23, and24 of the heatingpipe 25 issue in this room at the points 26 and 27. Theheated and burned gasesv flow in through these orifices, and combinewith the fresh air to be conveyed to the fireplace. There thetemperature increases the draft and produces a greater ventilation. Theside walls 9 of the grate 3 consist of fiat rods inclined downwardlyfrom the outside, so that the falling of ashes cannot take placelaterally, but only to the bottom of the grate.

Two pipes, which connect with the spiral pipes 30 and 25, commence torun from the points 28 and 29 in the inclined cover 11 of the furnace.The combustive gases generated in the replace 2 circulate around thespiral pipes 30 and 25 and pass along the cover 11 until they reach thepipe-orices 28 and 29. Continuing their course through the orifice 28they ascend in the pipe 30, which breaks through the cover 11, crossingthe chamber 31 in the shape of an arch, which chamber, closed by thecover of the furnace and the partition 11, has for its object tomaintain the heat produced there. Inits downward course the pipe 30breaks again through the cover 11 and leads downward as a shorter spiralpipe through the heating-chamber of the furnace. It is partially sunk inthe casing of the furthe iire. At the extremity of this coil it leadsdownward along the wall. It is converted into the heating-coil 21 andleads then upward again as pipe 30, where it forms a longer nace, sothat it is not entirely surrounded byy coil entirely surrounded by theire next to the shorter coil, the extremity of which, after having againbroken through the cover 11 and passing again through the chamber 31,leads oit as the heat-conducting pipe 30. In the first lower spiral ofthislonger coil the pipe is widened and given the shape of a retort, inorder to utilize the ire entirely and to create a quick expansion of thegases.

The smoke-pipe 25 commences at the cover 11 at the point 29. It alsopasses through the chamber 31 in the shape of an arch, and continu in g,breaking through the cover 1 1,-it leads downward, passing in the middleof the smaller coil 30, bending above the fireplace, and thence upwardthrough the middle of the longer coil 30 and downwardbetween the twocoils, near the wall of the furnace, until it reaches the place- Wherethe pipe' 25 is divided into the two branches 23 24 which issue in theheating-chamber 22. As this pipe 25 conveys again the burned smoke andthe stronglyheated gases into the grate of the same tireplace an intenseheat will be created.

Instead of the cleaning-doors 14:, I have arranged doors' or clacks l5in the coils 2l 25, in order to be able to clean the same over theirentire length.

I claim;

l. In combination, the grate, the superheating-chamber, thepartition-cover 1l, the heating-coil 21, the pipe 30 connecting with thecoil 2l and thence with an escape-pipe 30, and the pipe 2'5 conveyingthe smoke and `part of the basket-grate 3, the rear wall of the heatedgases from the top of the chamber 3 5 downward through the chamberbeneath the grate, substantially as described.

2. The described furnace consisting of a basket-shaped grate, an ash-pitthereunder, the heating or superheating chamber, a heating-coil 2l forthe air, of coils 25 and 30 in the iireplace, said coils commencing at apartition-cover l1 of the furnace, the shorter coil being surroundedpartially by the fire and connected with the heating-coil 21, a longer45 coil connecting with the shorter entirely surrounded by the fire,leading to the `heating escape-pipe 30' while the other pipe 25 passesthrough the middle of the coils 30 and between the same and iss ue inthe superheatingroom 22 at the points 26 and 27 divided in branches 3,24, and create thereby a circulation and heating of the' gases,substantially as described.

3. In combination' with the basket-grate 2,- a reserve grate arrangedunder the fire-'grate consisting of a bottom surface 4 extending upwardagainst the front wall 6 and pro-' vided with side walls which inclosethe lower 6o reserve grate being formed by the back of the chamber,substantially as described. Y

In witness whereof I hereunto set my hand in presence of two Witnesses.
